Abstract

Die vorliegende Erfindung ist auf eine Fahrzeugbewegungssteuerungsvorrichtung gerichtet, die eine Hydraulikdruckeinstellvorrichtung, die zwischen einem Hauptzylinder und einem Paar Radbremszylindern angeordnet ist, die in jedem von einem Dualhydraulikschaltkreis enthalten sind, und eine Überwachungseinrichtung aufweist, um eine Zustandsvariable des Fahrzeugs zu überwachen. Es wird bestimmt, ob ein Rad von den Rädern, die betriebsfähig mit dem Paar Radbremszylindern verknüpft sind, an der Innenseite einer Kurve gelegen ist, entlang der das Fahrzeug die Richtung wechselt, oder an der Außenseite der Kurve gelegen ist. Ebenso wird ein Zustand einer Fahrbahnhaltung des Rads bestimmt, das an der Innenseite der Kurve gelegen ist. Ein Sollwert für das an der Außenseite der Kurve gelegene Rad wird zumindest auf der Grundlage der Fahrbahnhaltebestimmung eingerichtet. DOLLAR A Außerdem wird die Druckreguliervorrichtung als Reaktion auf ein Ergebnis eines Vergleichs zwischen dem Sollwert und der überwachten Zustandsvariablen gesteuert, um den Hydraulikbremsdruck in dem Radbremszylinder zu regulieren, der betriebsfähig mit dem an der Außenseite der Kurve gelegenen Rad verknüpft ist, wodurch das Fahrzeug sanft verzögert wird, wenn das an der Innenseite der Kurve gelegene Rad sich von der Fahrbahn gelöst hat.The present invention is directed to a vehicle motion control apparatus having a hydraulic pressure adjusting device interposed between a master cylinder and a pair of wheel brake cylinders contained in each of a dual hydraulic circuit and a monitor for monitoring a state variable of the vehicle. It is determined whether a wheel of the wheels operatively associated with the pair of wheel brake cylinders is located on the inside of a curve along which the vehicle changes direction or on the outside of the curve. Also, a condition of a road holding of the wheel is determined, which is located on the inside of the curve. A target value for the wheel located on the outside of the curve is set at least on the basis of the road holding determination. Also, in response to a result of a comparison between the desired value and the monitored state variable, the pressure regulator is controlled to regulate the hydraulic brake pressure in the wheel brake cylinder operatively associated with the wheel located on the outside of the curve, thereby gently decelerating the vehicle when the wheel on the inside of the bend has cleared the road.
